hello, i have some data within a mysql DB and i can show a ' linechart - drawPlotChart' with up to 10000 records. but if i have more than the chart is not showing up i need to plot up to 500000 data points. no i can not sum/avg/... the data - because i need to see the spikes and need to fokus on the spikes. i tried client side charting (like highcharts) but there the limit is apx. 50000 with rendering in the browser - so i believe it must be possible to render more than 10000 if running on a server... any idea or help would be great thanks holli |

It will spend too much time to generate png, then the php dead? if the png can be created by every 1000 points , and piece together the 10 piece, we will can get a big png with 10 small png file link to show the plot detail. |
