But it should also work with many points. The line is drawn between the data points. If you have many data points that are plotted close to each other, the actual style of the line (solid, dotted, etc.) cannot be resolved. If you zoom in you should see the difference. For many data points the line style or drawing the line at all is not relevant because this cannot be resolved anyway. To be able to resolve we'd need to drop many data points, i.e. don't plot them. This can work for some well-behaved functions like x^2 where not so many data points are required to get a reasonable results. But for noisy data withe many outliers it's not immediately clear which data points to drop. If the user requests to plot 10k data points on a small area, wants to really see all of them and wants to clearly see the dotted line, here I don't know how this should work... > A relevant question is also: would it be posible to choose some > interpolation styles between the points (may be also usefull for svg > rendering)? We have different interpolation methods. Click on the xy-curve, go to in the properties explorer to the tab "Line" and select one of the interpolation methods under "Type". Is this what you're looking for? -- You are receiving this mail because: You are watching all bug changes.
