hi thanks but thats not the case perhaps i described wrong the file look like this (the first column is identifier that the value is positive or negative) and the second column with actual value: pos 0.20 neg 0.17 neg 0.43 pos 0.13 pos 0.27 neg 0.19 neg 0.49 pos 0.12 . . . . so on to about 20 entries – i know how to put time on x-axis(referenced from another tutorial) and display its graph however with randomly generated numbers but not from a file. thanks
hi, thanks for reply so the file is an outcome of MATLAB which when opens has two columns separated by space and has about 20 entries..the file will be stored on same computer and is refreshed every 1sec. from canvasJS threads i was able to come up with a solution to display randomly generated numbers in a graph but now its to be dealt with a file with real data. looking forward for reply thanks
