Hi. I'm building something similar to the profitability analysis demo SAP provides here: http://www.sap.com/solutions/sapbusinessobjects/multimedia/demos/Profitability_Analysis.swf
One difference is that I am using a list box to select data by year (user can select 2009, 2010, 2011, etc. from this box, and the horizontal progress bars will display data for the year selected, using dynamic visibility).
I would like to have a horizontal slider available to change "r&d expenses" for example, as a percent of sales. In each year, I'd like the preset value to be different. For example, in 2009, I'd want the preset to be 50%. 2010 might be preset to 35%, 2011 might be preset to 25%, etc. From there, I would like the user to be able to move the slider to adjust that percentage for the selected year.
I have this working mostly, with the following issue: unless the mouse movement is precisely horizontal, the slider will revert instantly to the preset value. A user has to be super careful to move the slider, otherwise it reverts, and this is pretty frustrating.
To help make this less frustrating, I though I'd add a spinner for the same parameter. (A user should then be able to use the spinner to adjust the percentage for R&D expense, in case the very touchy slider is too frustrating). However, the slider always reverts to the preset. Click up, it reverts. Click down, it reverts. I can't figure this one out.
So the only way I can let the user adjust the parameter is with the horizontal slide, and it requires surgical precision.
Does anyone know what I can do to make this a little more smooth? I guess I have two problems that I see, the very touchy slider, and the uncooperative spinner. I have the slider with a min of 0 and a max of 0.5, and the increment is 0.05. Same for the spinner.
Many thanks, and let me know if there is some additional information I left out that would be helpful.
