Detailed Description

Base class for ECharts.

To add values, call addDataSet(). How the values are treated or how many data sets you can add, depensd on the specific implementation.

Your chart should be drawn in your implementation of drawChart(). This function is called by paintEvent() and also by exportChart() to paint the chart on an image. Therefore, you should only use the given view port size within this function.

To add an export action to your context menu or something else, just call exportAction() to create the action.

If you must draw text within your subclass, use labelFont or may be titleFont.

Constructor & Destructor Documentation

EChartBase::EChartBase ( QWidget * parent = NULL )

Here is the call graph for this function:

Member Function Documentation

void EChartBase::addDataSet	(	EChartValues	dataSet,
		const QString	label,
		QColor	color = `QColor()`
	)

Adds a new line to the graph.

If x-ticks and y-ticks are not numeric, x- and y-values can only contain values from x-ticks and y-ticks.

If color is empty, a default order is used.

This slot is called, if the context menu of this chart should be shown.

You may reimplement this function, if you need another menu than the default one.

Function to draw the chart.

It is called by the overladed paintEvent() function and also used to export the chart into an image.

Note: Make sure to restore the painter afterwards!
