Post line chart with more than 10000 plots
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.
