The data within a table can be plotted graphically. A histogram can be made for the data within one column or a plot can be constructed for the data within two columns.

To make a plot, histogram or heatmap:

• Read in a chemical spreadsheet or other data in spreadsheet form (e.g. csv).
• Click on the plot button at the side of the table (shown below).

8.4.1 Column Histogram

To plot a histogram of the data within one column:

• Select the column by clicking on the column header.
• Right click on the column header.
• Select the Column histogram option.

A plot will then be displayed next to the table.

8.4.2 Histogram Options

Once you have created a histogram you can change the following parameters by right clicking on the plot and selecting options

Options:

• Change plot title.
• Change the data source using the drop down button and select another column in the table.
• Change the histogram bin size.
• Change the bars positioning from vertical to horizontal.
• Change the bar relative width compared to bin size. Bigger values give thicker bars.
• Color the bars

8.4.3 Histogram Bins

There are two ways to change the bin size. 1. Using the options dialog box or 2. interactively by left clicking and dragging at the top of the plot as shown below - this will allow you to find the best density estimation picture.

8.4.4 Plots

To construct a scatter plot from data within two columns:

• Click on the plot options button (right hand side of table).
• Select the data from the drop down options in the Data section of the dialog box. There are additional options to change the color, mark shape or size, and grid and axis display.

8.4.5 Multiple Curves

Multiple curves can be added to a plot:

[ Heatmap Example ]

To generate a heatmap:

• Read in a table containing the data.

• Click OK.

8.4.6.1 Heatmap Example

This example shows how you can place a fully interactive heatmap next to a tree.

• Select numerical columns by clicking on the column header and holding CTRL key.
• Right click on the column header and choose "Reorder by Clustering".
• Click on the cluster button on the right hand side of the table and use the default options.
• Right click in the cluster and "Change Record Labels"
• Check color check box and click 'Add All Numerical'
• Remove cluster related columns from the end ('cl' 'ord', etc ...)
• Click OK a tree and heatmap as shown below will be displayed.
• CTRL +/- allows you to zoon in and out.

8.4.7 Pie Chart

To generate a Pie Chart:

• Read in a table containing the data.
• Click on the Plot/Histogram button on the side of the table or right click choose Options on a plot.
• For Histogram choose Plotting Style > Pie radio bin. Number of bins/sectors can be controlled the through the 'Bin Size' parameter. For Plots choose Points > Plotting Style > Pie 'X' should be discrete (integer or string column with categories), 'Y' - any numerical column.
