Adjust axis plotly r

Till now I was styling the graphs in Photoshop rather than prepare them properly in RStudio sooo lame, huh? But I decided it's time to learn how to do it, so here is the little tutorial about making a plot beautiful using only R and plotly package. We'll gonna play with San Francisco average monthly temperatures availaible here.

Every aspect of a plotly chart the colors, the grid-lines, the data, and so on has a corresponding key in these call signatures. This page contains an extensive list of these attributes. Plotly's graph description places attributes into two categories: traces which describe a single series of data in a graph and layout attributes that apply to the rest of the chart, like the title, xaxis, or annotations.

Here is a simple example of a plotly chart inlined with links to each attribute's reference section. Now we can start styling it! Here you can check all possible layout properties. I chose a nice, royal blue. If you did too, you can now see that the plot became completely unreadable. Now we can proceed to styling X and Y axis. As both xaxis and yaxis will have many arguments, we will wrap them in list.

Axes and Text

See below:. How about adding some text, so we would know what are we looking at? You can read more about it in previous postsection Factors and Levels. To rotate, add to xaxis a tickangle key. Much better. Here is the answer. We nearly have it, we are only missing the general title and some font styling.

Again, we will wrap arguments in list. Read more about title font here. I chose the Agency FB font, you can use anything that is present in your operating system.R in Action 2nd ed significantly expands upon this material.

Many high level plotting functions plot, hist, boxplot, etc. For example. Many other graphical parameters such as text size, font, rotation, and color can also be specified in the title function. Add a red title and a blue subtitle. Text can be added to graphs using the text and mtext functions. To practice adding text to plots in R, try this interactive exercise. Other common options are cexcol, and font for size, color, and font style respectively. You can use the text function see above for labeling point as well as for adding other text annotations.

Specify location as a set of x, y coordinates and specify the text to place as a vector of labels. The x, y, and label vectors should all be the same length. You can add mathematically formulas to a graph using TEX-like rules. See help plotmath for details and examples. If you are going to create a custom axis, you should suppress the axis automatically generated by your high level plotting function.

Here is a somewhat overblown example. The minor. Add minor tick marks library Hmisc minor. The length of the major tick mark is retrieved from par "tck". Other graphical parameters such as line type, color, and width can also be specified in the abline function.

Other common legend options include bty for box type, bg for background color, cex for size, and text. For more on legends, see help legend. The examples in the help are particularly informative. Try the free first chapter of this online data visualization course in R. Kabacoff, Ph. Axes and Text Many high level plotting functions plot, hist, boxplot, etc. Titles Use the title function to add labels to a plot. Common options are described below. Alternatively, the text can be placed interactively via mouse by specifying location as locator 1.

Labeling points You can use the text function see above for labeling point as well as for adding other text annotations.

Axes You can create custom axes using the axis function. Reference Lines Add reference lines to a graph using the abline function.

Legend Add a legend with the legend function.You can configure appearance of each axis by specifying the line width and color. It is also possible to define grid width and grid color. Let us learn about the same in detail in this chapter. The tickfont property is a dict object specifying font name, size, color, etc. The tickmode property can have two possible values — linear and array.

If it is linear, the position of starting tick is determined by tick0 and step between ticks by dtick properties. If tickmode is set to array, you have to provide list of values and labels as tickval and ticktext properties.

We now format the Layout object in above example to configure x and y axis by specifying line, grid and title font properties and tick mode, values and font. Sometimes it is useful to have dual x or y axes in a figure; for example, when plotting curves with different units together. Matplotlib supports this with the twinx and twiny functions. In the following example, the plot has dual y axesone showing exp x and other showing log x.

Plotly - Format Axis and Ticks Advertisements. Previous Page. Next Page. Previous Page Print Page.Most graphs consist of a horizontal axis x-axis and a vertical axis y-axis to display their data. This tutorial will show you different ways you can define axes properties. The axes are autoscaled, but if you want you to change the range of your axes, click 'Custom Range' under 'Selection'. For our example, our y-axis values are over 15 so we'd like our y-axis to start at 10 our minimum value.

We'll click on 'Y' and then enter the minimum value in the 'Min' field. This can be done if we have a maximum value, by entering it in the 'Max' field. Reversing the axis is so easy; just flip the 'Min' and 'Max' values. The animated image below shows that when we switch the 'Min' and 'Max' values, the axis is reversed. You can also set the axis type as linear or log. Customizing the style and number of tick labels along the axes can help highlight particular aspects of your data.

The tick labels reflect column values that were selected in your trace s. You have the option of showing these labels or hiding them. When the tick labels are set to 'Show', you can change their typeface, font size and font color.

Note that certain colors and typefaces are only available with a PRO subscription. Click here to upgrade!

You can also add exponents, but it'll only work if your axes consist of numerical data. You can add a prefix or suffix to your tick labels. If yours isn't listed, click on 'Custom' and type it in the field.

For our example, our y-axis consists of data in Celcius, and our x-axis is in minutes. Once you've selected or entered a prefix or suffix, click the icon next to 'Label Positioning'. A modal will open with a few selections. You can place the prefix or suffix for the first or last tick label, all ticks, or none. To set the number of ticks, go to 'Axes', and select the number from either 'Tick Labels' or 'Tick Markers'. The markers are hidden under 'Tick Markers' by default, so click 'Inside or 'Outside' to view the options.

You can set them as 'Linear' or 'Custom' in the same section. The plot below had the dates on the x-axis set as biannual. We'd like to show every consecutive year, so we select 'Custom' and enter the desired number of markers in the field.

When you work with date or time series plots, you have to convert the date for the step size and set offset. Let's say you set ticks on the 15th of every third month, set the 'Step Size' to '' and 'Step Offset' to 'M3'. To set ticks every 4 years, set it to 'M48'. Our plot display our data every year, so it's been set to 'M12'.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

This is not easy to do in R, but it can be done. By default, R displays a value at each tick mark and the values for each axis appear to sit on a line parallel to the axis. If we want to adjust the labels on the horizontal axis, we must first alter our graphics parameters so that we suppress the horizontal axis that usually appears with the graph.

First, we save our current settings for the graphics parameters so that we can restore them later. We have effectively cleared the horizontal axis, making room for us to add in the labels of our choosing at the angle of our choosing. We create a vector of the values of the labels we wish to add and we indicate in the axis command where we want tick marks to appear and that we do not want labels automatically added at the tick marks.

For details on each of these and the other options, look at help axishelp textand help par in R. If we wish to similarly format our vertical axis labels and label the values with character strings, we would need to replot the graph suppressing both axes and then layer on the x and y labels with our specified angles and values.

The code below provides an example. We define a vector of the strings we wish to use as labels on the vertical axis lablist. We also need two different text statements in which we specify that the which values are for either the x or y axis.

Determines whether or not this trace is visible. If "legendonly", the trace is not drawn, but can appear as a legend item provided that the legend itself is visible. Sets the legend group for this trace. Determines the drawing mode for this scatter trace. Otherwise, "lines". Assigns id labels to each datum. These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type. Builds a linear space of x coordinates. Builds a linear space of y coordinates.

Sets text elements associated with each x,y pair. If a single string, the same string appears over all the data points.

3D Axes in R

If an array of string, the items are mapped in order to the this trace's x,y coordinates. Template string used for rendering the information text that appear on points.

Sets hover text elements associated with each x,y pair. Determines which trace information appear on hover. Template string used for rendering the information that appear on hover box. Assigns extra meta information associated with this trace that can be used in various text attributes. Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, "scatter" traces also appends customdata items in the markers DOM elements.

Sets a reference between this trace's x coordinates and a 2D cartesian x axis. Sets a reference between this trace's y coordinates and a 2D cartesian y axis. Sets the stacking direction. With "v" "h"the y x values of subsequent traces are added. With "fraction", the value of each trace at each location is divided by the sum of all trace values at that location. If blank or omitted this trace will not be stacked. You can only stack on a numeric linear or log axis.

Sets the marker symbol type. Adding is equivalent to appending "-open" to a symbol name. Adding is equivalent to appending "-dot" to a symbol name. Adding is equivalent to appending "-open-dot" or "dot-open" to a symbol name. Sets the scale factor used to determine the rendered size of marker points. Sets the minimum size in px of the rendered marker points.

Sets themarker. Sets the lower bound of the color domain.
