How to draw grid lines with given values

[Larry]

Hi

I have an RSI line chart and the grid value range is from 0 - 100. I need only two grid lines with values 20 and 80. Currently the grid lines are generated automatically but not at 20 and 80.

Thanks

Larry

Hello Larry,

probably the easiest way to achieve what you want is to use 'custom labels,' e.g.

Code: Select all

        private void InitializeChart(TChart chart)
        {
            Random rnd = new();
            Line line = new(chart.Chart);
            for (int i = 0; i < 20; i++)
            {
                line.Add(rnd.Next(0, 100));
            }

            chart.Axes.Left.Grid.DrawEvery = 1;
            chart.Axes.Left.Labels.Items.Add(20, "20");
            chart.Axes.Left.Labels.Items.Add(80, "80");
        }

Which here gives me this chart:
