Hi Lio,
In Chare web you can print the chart without using the Tool bar by using the below code snippet:
Size chartSize = new Size((int)Math.Ceiling(this.ChartWebControl1.Width.Value),
(int)Math.Ceiling(this.ChartWebControl1.Height.Value));
Bitmap bmp = new Bitmap(chartSize.Width, chartSize.Height);
ResourceHolder printHohlder = new ResourceHolder(this.Page);
ImageResourceInfo iri = new ImageResourceInfo(bmp, ImageFormat.Png, this.ChartWebControl1.Parent.ID);
this.ChartWebControl1.Draw(bmp);
printHohlder.AddResource(iri);
ChartUtils.PrintImageOnClient(this.Page, printHohlder.GetResourceUrl(iri));
Please have a look at the sample from the below link which illustrates the above:
