If you have a Team license, you can add your own logo to your chart and dashboard exports. Note the new logo will appear on your entire team's chart and dashboard exports. Click on the gear icon in the far right to enter the profile page.
From there, select the CUSTOM LOGO option to upload a SVG file representing your logo. DataHero requires a SVG file format, because it allows your logo to look sharp at any resolution. We recommend your custom logo have an aspect ratio of 3 x 1, width to height. Also, we suggest you snap your logo's art board to the edges of your logo, minimizing any unnecessary empty space.
