Hi Basundhara
Thanks for warmly welcome!
Our requirement is...
If you look at the image of the bar chart in ErrorMargins.jpg
each bar has a little line (error margin) at the end of the bar, this is another attribute/value associated with the bar value.
An uncertainty in the value. ie the value could be in the range of this attribute
Also on the multi-series line chart. At each value plotted ther is a corresponding vertical line on the y-axis, which is an attribute/value associated with the value that is displayed. This is displaying the possible range of the value.
E.g. a bar on the chart could have a value of 75 but this value could be as high as 77 or as low as 73 so bar value would be 75 with an error margin of + or - 2. With 2 being the error margin.
I'm hoping that clears things up a bit, but probably confused it further ;-)
This is used by statisticians who have got some data to display on a chart but also have to display how accurate there data is.
Regards
Scott
