Grouped Bar Chart

Data:

There are two ways of defining data for Grouped Bar Chart. You can use a CSV file formatted in the following manner:

• First row is always Headers. Headers contain names of individual bars in each group. So in our example its Level 1, Level 2...etc.
• All of the consecutive rows are considered data points. These are all of the Groups with each row starting with a Group Name and then values for each data point (in our case Level).

Example of CSV data:

Another way to define data is to generate it from a list directly in Dynamo. You can do it like so:

Style:

There are couple of things that you can define for the appearance of the Grouped Bar Chart. First is a BarHoverColor. That's a color that a bar will change to when you hover your mouse over. You can use a Dynamo Color node to define that input or you can use the Design Script syntax like so: DSCore.Color.ByARGB(1,100,100,100). Second input is a list of colors. Each bar inside of the Group can have a specific color of your choosing, or if you supply a null value the default color scheme will be applied ([D3 Categorical Colors] (http://bl.ocks.org/aaizemberg/78bd3dade9593896a59d)). Category20c is the default color scheme. Remaining inputs are integers for Width and Height (default values are 1000px x 500px) and a string for YAxisLabel.

Tip:If you are not specifying a custom range of colors to be used for this chart, please make sure to feed in a null value to the Colors input. It will cause an exception otherwise.

Grouped Bar Chart is not sorted. It is by default in order of your data input.
