Just one more note on this subject, if I add series.getMarks ().setVisible( false); to the pair of series being displayed, they both display on the first set of data. This gets past the data missing on first insert, however it is still very slow in displaying the bars and very slow to scroll.

I have tried to upload a few times today, and no success. At first it would drop the connection in a few minutes, now I am getting an error back from your web server "[HttpException (0x80004005): Maximum request length exceeded.]". Will try again tomorrow. I have altered my app to insert data throug...

More info. On further testing, I notice that series.add(v1, v2, Color.blue); executes very quickly. I have set chart.setAutoRepaint (false); before doing this and executed setMinMax before setting AutoRepaint to true again and then doing a chart.invalidate(); to get it to repaint. The big delay happ...

Two potential problems here. I can not post a complete app on a public forum, trade secrets and all that stuff. If you have a private way, that may be acceptable. Second, the data that adds the bar(s) is generated by hardware on the other processor in this design and sent to the Android display over...

Thank you much for the hint, however at this point, we are not doing anything with dates, but most likely will in the future although probably not on a chart. My speed problem is just adding simple pairs of bars to a chart with float y values and integer 1,2,3... x values. Takes over a second for ea...

Would it be possible to get a timeline for this? We, like everyone else I am sure, have a project with a deadline.

Thank you for the reply. Our app needs to display a bar chart of pairs of data as they happen. The pairs could occur as frequently as twice a second or could be separated by many seconds per pair. The two pieces of data in the pair may be separated from each other in time by several hundred millisec...

I really don't care about the simulator, almost all of my testing will be on an actual device. A bit more testing, first instantiation of a chart takes 15+ seconds on our hardware, subsequent opens of the activity with the chart in it take about 1 second +/-, that is probably acceptable. I will prob...

I notice that the Java source installer doesn't want to activate through a proxy, forcing me to run it on a PC outside the corporate firewall to activate and get the source. It should be a relatively easy fix to make it use the system proxy settings on a Windows PC.

Tested with the demo and get the same results. Sorry it took a while, I had only tested the demo on the simulator until now and always assume that will be slow. I was on the road yesterday and did not have hardware with me. The very first iteration of the line "chart = new TChart(this);" which is li...

I need some suggestions to speed TeeChart for Android up a bit. I have the source version and am targeting Android 2.2 API 8 for a dedicated display (see http://www.touchrev.com/products/nimble/7-inch/). Without doing anything other than just instantiating a chart class with chart = new TChart (this...
