  1. Don't you mean for (int i 0; i < n; i++) { chart.Data.X[0,i] = <x>; chart.Data.Y[0,i] = <y>; } for (int i 0; i < m; i++) { chart.Data.X[1,i] = <x>; chart.Data.Y[1,i] = <y>; } We'll try this. We tried the cross table provider in the latest version and that seemed to work but was horrendously slow. We had 76640 points on series 1, the same on series 2 and then 30 on series 3. It took about 3 minutes to show the chart So....just so I'm clear. Do I put the timestamps on the x axis and the values on the Y with your API example? for (int i 0; i
  2. If we had the example data in a dataset could we just assign it to the datasource property of a chartfx instance?
  3. We have been using the API to add the points in code as we could not find out how to add them via data sets or any other manner. All the chartfx documentation talks about equal numbers of x and Y points per series so how do you do this? The number of data points depends. We could have 1 series with 86000 points per day and another with only 30 for the same time period. The problem is we are having to pad out the series with only 30 points into the full 86000 to match the other series. That's the performance issue.
  4. We have been using Chartfx for quite some years now and have run into major limitations in how chartfx actually gets data. We now use a system of exception reporting to save our system data. That means that for a given series over the day if there have only been 2 changes only 2 data items are stored in the database. Another series item may have changes 300 times for the same period so trying to plot both these series items together with Chart fx means that we MUST create arrays of the same size. This has an obvious performance drawback. We have been experimenting with other charting solutio
