displaying multiple tags on chart

[Former Member]

Hi,

i have a table with coloums date/time, tagval ,tagindex. i can display a linechart with tagval(y-axis) and date/time(x-axis) by passing tagindex as a parameter at runtime to the query template.Each time the tagindex change,graph in the chart will also change,new tag with tagval and date columns will replace the old one.

My requirement is i want to show the tag for the past tagindex and present tagindex.with one column how can i display multiple tags simultaneously.

please help me.

points will be awarded for the feasible solution.

Hi.

Does your table (or another table that we can join on tagindex) have the tag name in it? If so, we can easily use the data mapping page in the display template editor to assign the tagname column and the value column, and you should be able to meet your requirements.
