Chart Custom Symbol

The Chart Canvas element's Chart Custom Symbol child element allows you to add a predefined shape or symbol for the chart marker.

A "marker point" is a symbol that appears on the chart at each data point. The Marker Points element enables customization of Marker Point appearance, with its Symbol attribute specifying the symbol that identifies each data point on the chart. With Chart Custom Symbol, you can create your own symbol and utilize it in the Symbol attribute of the Marker Points element.

The Chart Custom Symbol element has the following attributes:

Attribute	Description
SymbolKey	The key or ID of the custom symbol. This key links the custom symbol to the Marker Points element's Symbol attribute list.
SymbolPath	A string representing the Scalable Vector Graphics (SVG) path, written as follows: Separate commands and parameters with commas. Parameters can be numerical values or expression with variables x(x coordinator of plot area), y(y coordinator of plot area), w(graphic’s width), h(graphics’s height). For example: M, x, y, L, x+w, y+h, V, y+h*0.5, H ,x, L ,x, y

4. Access the Marker Points element and enter or select the SymbolKey (added in step 2) in the "Symbol" attribute.
