Solid and dashed lines not distinguishable

I've uploaded two images: dashes-image01.png & dashes-image02.png.

Image02 shows a chart with two series. One series is supposed to be solid and the other dashed. It is very difficult to identify which is which.

Image01 shows a chart with the same two series. It is easier to see the difference between the solid and dashed lines, but only because the chart is bigger.

If we increase the number of samples or shrink the size of the chart the less distinguishable the solid and dashed lines become.

On a polar chart the dashes practically become a solid line near the center of the graph.

Hi Christo,

I'm afraid your problem is the same as described here:

An option could be reducing the number of points in your series using DownSampling function as shown in the All Features\Welcome !\Functions\Extended\Reducing number of points examples at the features demo, available at TeeChart's program group.
