[randy.xia]

TeeChart for NET Std Business Edition,Legend.checkboxes is out of date, prompting to use ActiveStyle, but the function can not be realized by using ActiveStyle, why is this? How to solve it?

Hello, thanks for asking.

You can still use the deprecated approach 'tChart1.Legend.CheckBoxes = true", but it is very recommended to use the ActiveStyle property instead.
This is how to use the ActiveStyle property:

Code: Select all

 tChart1.Legend.ActiveStyle = LegendActiveStyles.CheckBox;

Here's a quick example:

Code: Select all

private void ChartSetup()
        {
            //Example with two lines, different color
            Line myLine = new();
            myLine.Color = Color.Red;
            Line mySecondLine = new();
            mySecondLine.Color = Color.Blue;

            //Fill data
            for (int i = 0; i<10; i++)
            {
                myLine.Add(i, 2 * i);
                mySecondLine.Add(2 * i, i);
            }

            //Adding lines to Chart
            tChart1.Series.Add(myLine);
            tChart1.Series.Add(mySecondLine);

            // Set the legend's active style to checkbox, as desired.
            tChart1.Legend.ActiveStyle = LegendActiveStyles.CheckBox;
        }
        

This code will create a chart like this one:
