Time value in tooltip
posted

I've got a line chart where time is plotted on the X axis, and I can't figure out how to get the time value and format it in my IRenderLabel implementation for the tooltip.  I don't see anything in the docs that appears like it would work.  I tried DATA_COLUMN, but it seems to just be a column index and not the X coordinate value.

Thanks!

     try TIME_VALUE.

     

    here's a little code trick to view all the label keys/values in the tooltip context...

            private void Form1_Load(object sender, EventArgs e)
            {
                Hashtable labelHash = new Hashtable();
                labelHash.Add("MY_LABEL", this);
                this.ultraChart1.LabelHash = labelHash;
                this.ultraChart1.Tooltips.FormatString = "<MY_LABEL>";
            }

            #region IRenderLabel Members

            string IRenderLabel.ToString(Hashtable context)
            {
                foreach (object o in context.Keys)
                {
                    Console.WriteLine(o.ToString() + " // " + context[o].ToString());
                }
                return "hi";
            }

            #endregion
