Tolbase crash graphing series with a lot of data

[jgarcia]

Good morning.

Tolbase crash trying to graph a serie with lot of data.

Serie SubSer(CalInd(Hourly,Hourly),y2001m01d01,y2008m02d10h23i00s00.000);

Sometimes Tolbase can graph this serie but in this case, if you try to change axis serie options and Hourly is selected, applying this change make Tolbase crash

This is the piece of code that make tol abort:

if (axisPtr->t1Ptr->nTicks > MAXTICKS) {

fprintf(stderr, "too big, %s major ticks can't be %d\n",

axisPtr->name, axisPtr->t1Ptr->nTicks);

abort();

}

I don't like this way of deal with errors. But now we can no fix inside blt, so we must restrict the number of ticks we can show at the X-axis,

I'll try to make a patch in tcl source in order to prevent the previous situation,

I think that a convenient solution, and transparent for end user, could be to divide the requested number of ticks T by the maximum period P matching T/P <= MAXTICKS. So, user will see a periodic intervalation o original one. For example if MAXTICKS=20000 and you ask for 80000 hourly ticks, then taking P=4, the chart will show 20000 4-hourly ticks without any problem. In this way, no error message is needed and you should need a monitor with 20000*6 horizontal pixels to view this number of ticks.

the approach proposed by Victor has being applied, and a solution is at CVS

now I want to see that monitor you mentioned!!!!!, jejeje
