You’re free to define the configuration of a chart legend, including its shape and position. Depending on the chart type, you can set a form of the legend markers, define paddings between legend items, assign vertical and horizontal alignments of the legend block, etc.

You can create a treemap chart to visualize data in hierarchical order as a set of rectangular tiles. The size of treemap tiles is proportional to the values of the data items they represent. Users can arrange tiles into groups and expand/collapse them by clicking on the tiles.

You can easily make changes to the charts UI with the help of our API. Thus, you may repaint any chart element, add a gradient, as well as apply custom margins and paddings. You can also add different point types, create a base line, and set up templates for scale labels. Moreover, the DHTMLX bar chart allows you to add a template to values that are displayed for data items in bars.

The Chart API allows you to perform various operations with data items. For instance, you can configure your chart to display more data items on the fly. A new item is added relative to the X-axis.
