If you can't resist the urge to play with the data, we have new charts at Pollster.com that can satisfy your need. These are interactive versions of the charts here and previously at Pollster. You can exclude pollsters or methods. You can change the sensitivity of the fit to either more sensitive or less sensitive than our standard fits here.
Here is a sample chart for Ohio, using our default values:
And here it is again but mail and Internet polls excluded and more sensitivity:
Give it a try and let us know if you run into any problems. You can embed the results of your experiments on your own page, though not the interactive features.
At the moment the embedded graphs are scaled at 450 pixels wide. To fit them here I edited the html code to make the width 400 and the height 308. I hope we can automate that soon, but meanwhile if your width is fixed and below 450, changing two lines in the embedded html will fix it for you.
These charts are available for a growing number of states at Pollster.com. Stop by and play!
