Hello, given the following three columns in a mysql-database: timestamp(long), a(double), b(int). I now want to create a multi axis chart with two line charts: timestamp -> a , timestamp -> b. Basically the chart is working and all the data is drawn. Unfortunately the amount of datasets is quite large which leads to several thousand category axis tick labels. The fact that each label is drawn renders the entiry axis-labeling unreadable (a black bar). I am looking for a way to draw every value into the chart but only draw each n-th category axis tick label. Is there any way to do this? Help is highly appreciated. Thanks in advance.
