Hi, 1. Charts takes sigle point value like plotting DC voltages, Graph takes set of values like arrays (1D) which are plotted on Y-axis with respect to x axis which is integer number like 0,1,2..etc.. , XY graph takes bundled array of X-axis & Y axis.
2. Charts are used where a single point value is to be presented/updated w.r.t. to time or x scale (x scale can also act an index). Also it supports update modes like sweep, scope & strip. 3. Graph are used to plot waveforms which does have no. of samples acquired from DAQ board or other source, which needs to be plot on Y-axis. Main inputs of waveforms are starting time (t0), time stpes(dt) & Y elements. 4.X-Y graphs are used where you want to plot Y elements w.r.t. to the defined X elements. For e.g. I want to plot as Y=10 when X = 0 Y=20 when X = 2 Y=30 when X = 3 etc. Here we have one array of Y elements & other array of X elements. So bundle your X & Y array & fetch to XY graph to plot it. Hope it clears you the concepts. Your feedbacks are welcome. Best Regards, Nirmal Sharma India
