Different background color for different x-axis range

[pw]

Hi,

Is it possible to have different background color for different x-axis range? For example, my x-axis is a date & time scale, say from 1-Apr-09 00:00 to 3-Apr-09 23:30'. I want the background to have different shades for time range between 05:00 to 17:00.

Thanks.

Hi pw,

I think that the easiest solution would be using ColorBand tool. Could you take a look at the demo at Welcome !\Tools\Color Band?

Note that you should set them as vertical doinf something like this:

Code: Select all

colorband1.Axis = tChart1.Axes.Bottom;

Hi,

Revisiting an old question I had. What would be the easiest way to setup the ColorBand if I want to have different color backgrounds for weekends?

I'm not sure how I can loop through the x-axis, figure out which is weekend & setup a ColorBand for each weekend.

Please advise. Thanks.

Hi pw,

Here you have a simple example of how you could do it:

Code: Select all

            tChart1.Aspect.View3D = false;
            Steema.TeeChart.Styles.Candle candle1 = new Steema.TeeChart.Styles.Candle(tChart1.Chart);
            candle1.FillSampleValues(25);

            for (int i = 0; i < candle1.Count; i++)
            {
                if (DateTime.FromOADate(candle1.DateValues[i]).DayOfWeek == DayOfWeek.Saturday)
                {
                    Steema.TeeChart.Tools.ColorBand colorband = new Steema.TeeChart.Tools.ColorBand(tChart1.Chart);
                    colorband.Start = candle1.DateValues[i];
                    colorband.End = candle1.DateValues[i] + 1;
                    colorband.Axis = tChart1.Axes.Bottom;
                    colorband.Transparency = 50;
                    colorband.Pen.Visible = false;
                }
            }
