Hello,

I want to include text within charts, for example, on a horizontal bar chart a data value (not necessarily the plotted one) to the left (if<0) or right (if>0) of the bar.

In order to calculate the position of the text I need to know the chart's axis range and I would like to know what is the formula that you use for determining the max/min and step size when the automatic option is selected. Would you be so kind to reveal it?

Thanks,

Javier

The algorithm is quite complicated, and cannot be summed up easily.

Is there a way then to know what is the range of a given chart?

Excel apparently uses this algorithm:

We offer a command to set the min/max, but not a routine to retrieve it.

Hi Pamela,

Is this feature (retrieving max/min values of chart) something you could include in future releases/patches?

Thanks,

Javier

Hi,

Is it possible yet to retrieve the minimum and maximum values of the range of a graph axis, when these are automatically chosen by Eviews?

Kind regards,

Unfortunately, no.

It is a pity that this functionality is not available. One of the possible uses is when you want to convert the dimensions [date,y-axis] of a chart to virtual pixels in order to assign text to a data point in a chart (say at the peak value of the NASDAQ add a text that says "peak") one can interpolate the x position via @pagesmpl but the y position is not possible unless the chart axis is set to minmax and this may not be what one wants.

It shouldn't be too difficult to assign to a graph object scalar attributes such as @minleftaxis, @maxleftaxis, etc.

We'll make a note of the suggestion. Thanks.
