delphi - TeeChart TLineSeries - Is it possible to draw multiple lines per series? -

is possible draw multiple lines single tlineseries using teechart? specify field in dataset series should grouping by, drawing 1 line per group. or not possible , series should added chart each group/line should displayed?

you accomplish setting xvalues.order lonone , adding null point each time want start new line. however, speed drawing , point handling tfastlineseries uses same color (seriescolor) points. if want utilize diferent colors individual points should utilize tlineseries instead.

uses series; procedure tform1.formcreate(sender: tobject); var i, j: integer; begin chart1.view3d:=false; chart1.legend.visible:=false; chart1.addseries(tfastlineseries) tfastlineseries begin xvalues.order:=lonone; treatnulls:=tndontpaint; i:=0 4 begin if i>0 addnullxy(0,0); //start new line addxy(0,random*1000); j:=1 24 addxy(j, chart1[0].yvalue[chart1[0].count-1] + random*10 - 5); end; end; end;

anyway, don't see why 1 above instead of creating several tfastline series.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
