Flot pie chart gives error in firebug: “uncaught exception: Invalid dimensions for plot, width = null, height = null”

Question

I using flot pie chart for plotting pie charts. but it shows error in firebug that

uncaught exception: Invalid dimensions for plot, width = null, heig

Answer 1

I had the same problem integrating template to rails. That's a bad way, but I just comment the line which throws the exception and add 2 lines to set width and height to 0 - it helped me.

Canvas.prototype.resize = function(width, height) {

  if (width <= 0 || height <= 0) {
    // COMMENTED NEXT LINE
    // throw new Error("Invalid dimensions for plot, width = " + width + ", height = " + height);
    // NEW LINES ADDED
    width = 0;
    height = 0;
  }

  // ... others code 
}
