![]() The pixel ratio is 1 by default and is 2 for higher resolution displays (ex. name here]/#/views//?:pixelratio=1 (any value 1 to 10) If the visualization is on Tableau Server or Tableau Public then you can set the pixel ratio as a parameter in the URL. Once in Adobe Illustrator you will have a vector graphic of the dashboard (except for the caveats listed above). You will notice that when viewing this file in a PDF reader that you can zoom in without pixelation (because the text and graph parts will be a vector graphic). One problem you may encounter with doing this is that you may lose your fonts and when opening an EMF file in Adobe Illustrator there is no font replacement warning as there is when opening a PDF as described next, so be sure to check your fonts. Exporting as an EMF is one of those ways, because it can be opened in Adobe Illustrator. The resolution is not very high, so we'll explore other ways to get a higher resolution. The PNG, BMP and JPG will give you a standard size image of the dashboard. This will allow you to save as PNG, BMP, JPG or EMF. Click on "Dashboard" (or "Worksheet") from the menu and the select "Export Image". The rest of the visualization can be rendered as a vector graphic or a high resolution raster image. User Interface components (specifically sliders and dropdown boxes) will not export, only the selections themselves will export. Map layers will be raster images (discussed more below).Ĥ. ![]() Custom shapes used in your Tableau viz will be raster images.ģ. This includes logos or other images added using the image object on a Dashboard.Ģ. Custom images used in your Tableau viz will be raster images. The goal of this post is to show you various methods for creating a high-resolution bitmapped image (PNG, JPG or BMP) or a vector graphic, which doesn't have the same limitations and can be converted to high-resolution if needed.įirst, a list of caveats, which will be common among most of these approaches when working with Tableau workbooks.ġ. Here is one example with a nice outline of each file type. You can find more information on-line about the various file types. PDF is another type of file that can be a bitmapped image or a vector graphic. This is a Windows specific file, but can be opened in other programs, for example Adobe Illustrator.Ĥ. Enhanced Metafile (EMF) is another type of file that can combine bitmapped images and vector graphics. Because they are calculated they can be enlarged without distortion, as they are not dependent upon the resolution of the image, i.e. Vector graphic use math to represent the image, the geometric patterns that comprise the image. When zoomed in too far the image will pixelate.Ģ. The higher the resolution, the better the quality of the image. ![]() Raster graphics (also called bitmapped or pixel graphics) have a 1-to-1 pixel representation of the image. Before I do that, a quick reference on image types.ġ. I will walk through the various options I explored and list the advantages and disadvantages of these approaches. The learnings here come from countless hours of work, so hopefully what I share with you can help you if the need arises. I've been meaning to post these methods in case others have this need. The source in most of these cases was a Tableau workbook. My end goal was to get the best image for print that I could create, preferably a vector graphic. In working on the Big Book of Dashboards with Steve Wexler and Andy Cotgreave, I had the need to have high resolution graphics for the book for two dozen dashboards and various other images.
