Chart & Statistics View
Chart View will generate bar plots, box plots, violin plots, scatter plots, and distribution graphs using any of the columns in a Visual Spreadsheet. Statistics, such as Welch's t-test, Pearson's and Spearman's rank correlation, and ANOVA will be calculated automatically.
To get to the chart view click on the icon indicated below by the red box or use the column menu and select 'Chart & Statistics'.
How to enter the Chart View
Once you enter Chart View, it will ask you a series of questions about what type of graph you are trying to make.
Compare subgroups will allow you to compare groups of patient's samples, either those that you have made or via a categorical feature, such as sample type. It will build the appropriate graph depending on whether you have selected a continuous numerical or categorical column. This option will let you make box plots, violin plots, and bar charts.
See a distribution will let you see a histogram distribution of the data in a single column. The column can have sub-columns, either multiple probes or multiple genes, which will instead create a plot with multiple box plots.
Make a scatterplot will make a scatterplot from two continuous numerical columns. The second column can have multiple sub-columns, either multiple probes or multiple genes, which will create overlapping scatterplots
If an option is grayed out, this means that you do not have enough or the right type of data on the screen. Return to the Visual Spreadsheet and add more data.
We show statistics in the upper right corner of the screen for most graphs. If we detect it will take some time run the statistics we may instead show a button with 'run stats', so that you can decide if you would like to run the statistical test.
Advanced options available under the graph will allow you to change the scales of the axes. If you are viewing a scatterplot it will also allow you to color the points by a column of data.
Note that for violin plots, the width of each plot is does not relate to the number of samples in the plot.
To return to the Visual Spreadsheet, click either the icon in the upper left, or the 'x' close button.
