hi
i'm working by discovery f746 board and i draw a graph to show the data that received from adc. i saved the data on the sdram then start to draw the graph by GRAPH_DATA_YT_AddValue() and related by value of data,set the scale and refresh graph.
in start of point every thing is good but after 10 seconds the graph move slow an slower.
when i don't reset scale and refresh graph by GRAPH_DetachScale() and GRAPH_DATA_YT_Clear() never graph will be slow.but i have to update scale that in this case graph work so slow.
what i have to do?
please help me.
thanks a lot.
