I try to made a chart (x:id,y:temperature) with data from a mySQL server using connector.
But somthing I do wrong, because the chart isn’t rendered at all.
I used the sample 05_line_chart/01_init.html and wrote a connector:
$chart = new ChartConnector($res, "MsSQL");
$chart->render_sql("SELECT * FROM `m_temperature` WHERE 1","log_id","row_id,temperature");
Could somebody help why it isn’t working? Or help with a working sample?
The file chart.log is not created.
The debug window isn’t shown.
But a sample with a grid connector is wortking stable.
