Try
AddTextColumn(Rept("|",LastValue(R2)),"R2bar",0,1,55,100);
where R2 is a calculated valueBest Regards Rick ________________________________ From: Mike <[email protected]> To: [email protected] Sent: Wednesday, May 20, 2009 12:37:50 AM Subject: [amibroker] Re: TJ - WishList - bar charts in cells of Explore Bummer. I'm getting rounding errors at 9 digits so that my 1's start turning into other values. It might be nice to see support for this by introducing a new format constant to the AddColumn function and doing the number of characters calculation internally. The output could then be done using '|' instead of '1'. e.g. AddColumn(ARRAY, Name, formatBarGraph) ; Ideally, negative values would be accepted too such that the valid range is -100..+100, centered at zero. We could then combine it with some color control (e.g. red negative values, green positive values) to get a nice looking bar chart column. |||| ||||| || ||| Mike --- In amibro...@yahoogrou ps.com, "Mike" <sfclimb...@. ..> wrote: > > I suspect that the more common request would be to have the function return > an array for bar by bar results. > > Based on that assumption, the problem with coding our own Rept function is > that we cannot add text, that changes bar by bar, to an exploration. > > In order to get an Exploration to give bar by bar output comparable to the > original graph we could use some creative coding and generate a graph using > the numerical values 1, 11, 111, etc. > > In the following example it is assumed that: > > - The values to be plotted have all been normalized to be within the range > 0..100 > - Floating point precision is limited to 16 characters and thus 100% can at > best be represented by 16 bars.
