How do I change my legend title?
Select your chart in Excel, and click Design > Select Data.Click on the legend name you want to change in the Select Data Source dialog box, and click Edit.
Type a legend name into the Series name text box, and click OK..
What is Barplot in R?
A bar chart represents data in rectangular bars with length of the bar proportional to the value of the variable. R uses the function barplot() to create bar charts. R can draw both vertical and Horizontal bars in the bar chart. In bar chart each of the bars can be given different colors.
What is Geom_bar Stat identity?
By default, geom_bar uses stat=”bin” . This makes the height of each bar equal to the number of cases in each group, and it is incompatible with mapping values to the y aesthetic. If you want the heights of the bars to represent values in the data, use stat=”identity” and map a value to the y aesthetic.
How do I add error bars in R?
Error bars can be added to plots using the arrows() function and changing the arrow head. You can add vertical and horizontal error bars to any plot type. Simply provide the x and y coordinates, and whatever you are using for your error (e.g. standard deviation, standard error).
Which function lets you set the title of the plot?
Directly by specifying the titles to the plotting function (ex : plot() ). In this case titles are modified during the creation of plot. the title() function can also be used. It adds titles on an existing plot.
How do I change the bar color in Matplotlib?
Use the color parameter to plt. bar() to change the bar colors in Matplotlib. color can be a scalar value to change the color universally or an array to change the color of each bar individually. Valid color values are documented in the Matplotlib color reference.
What is the difference between bar plot and histogram?
Histograms are used to show distributions of variables while bar charts are used to compare variables. Histograms plot quantitative data with ranges of the data grouped into bins or intervals while bar charts plot categorical data.
How do I change the width of a bar in R?
To make the bars narrower or wider, set the width of each bar with the width argument. Larger values make the bars wider, and smaller values make the bars narrower. To add space between bars, specify the space argument. The default value is 0.2.
What are Ggplot default colors?
By default, ggplot graphs use a black color for lines and points and a gray color for shapes like the rectangles in bar graphs.
How do you add color to a scatter plot in R?
The different color systems available in R have been described in detail here. To change scatter plot color according to the group, you have to specify the name of the data column containing the groups using the argument groupName . Use the argument groupColors , to specify colors by hexadecimal code or by name .
How do you change the color of a graph in Matplotlib?
1 Answer. The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. “r-” for a red line, or by explicitely stating the color argument.
What are the colors in python?
matplotlib. colorsb : blue.g : green.r : red.c : cyan.m : magenta.y : yellow.k : black.w : white.
How do I color a plot in R?
In R, the color black is denoted by col = 1 in most plotting functions, red is denoted by col = 2 , and green is denoted by col = 3 . So if you’re plotting multiple groups of things, it’s natural to plot them using colors 1, 2, and 3.
What is Ggplot default font?
Arial/Helvetica fontR and ggplot can create fantastic graphs, but the default Arial/Helvetica font is too boring and standard. You can change the font used in a plot fairly easily three different ways: All of the built-in ggplot themes have a base_family argument for setting the overall font family for the plot.
How do I import Ggplot into R?
The ggplot2 package can be easily installed using the R function install. packages() . The above code will automatically download the ggplot2 package, from the CRAN (Comprehensive R Archive Network) repository, and install it.
How do I increase space between bars in Matplotlib?
Use the rwidth parameter to plt. hist() to change the bar width. This value specifies the bar width as a fraction of the default width, and thus it cannot be larger than 1.
