contour legend bug?

[15696078]

When I add the series contour1 to tChart1 and click the legend, the program outputs an Exception.
To avoid this bug, is it possible to disable the legend click event?
Or is there another way?

Exception

Data for testing is as follows.

Code: Select all

            double[] Y = { 0.5067, 0.5126, 0.5053, 0.5044, 0.5108, 0.505, 0.5056, 0.5028, 0.5007, 0.5033, 0.5036, 0.5044, 0.507, 0.5045, 0.504, 0.5057, 0.4969, 0.5057, 0.5085, 0.5024, 0.5, 0.5058, 0.5111, 0.5094, 0.466, 0.503, 0.5012, 0.5161, 0.5096, 0.5076, 0.5054, 0.5023, 0.5045, 0.4987, 0.5031, 0.4995, 0.4996, 0.5065, 0.5038, 0.4939, 0.5098, 0.5011, 0.5112, 0.5095, 0.5079, 0.504, 0.4974, 0.5021, 0.4992, };
            double[] X = new double[Y.Length];
            double[] Z = new double[Y.Length];

            for (int i = 0; i < X.Length; i++)
            {
                X[i] = (i % 7) - 3;
            }

            for (int i = 0; i < Z.Length; i++)
            {
                Z[i] = (i / 7) - 3;

            }

            contour1.Add(X, Y, Z);

Hello,

Thank you for the bug report. I confirm that we can reproduce this problem for 3D Series for the latest build when Legend visible is true. We will check and fix the problem.

Update. The issue has been resolved for inclusion in the next update.

The problem relates to the LegendStyles.Palette setting for the Legend Style, hence a temporary workaround to be able to continue working could be to set it to "Values".

ie.

Code: Select all

tChart1.Legend.LegendStyle = LegendStyles.Values;
