- How can I read data from my database?
Grapher, Strater and Surfer allow data to be read directly from several sources, including Excel XLS and XLSX, dBase DBF, and Access MDB and ACCDB files. Use the File | Open command and select these files directly to create graphs and maps directly from the data. Other files, such as informatio ...
- Is there a way to overlay or update a map without reverting to the default scale and limits?
When you overlay or update maps, Surfer 9 and higher versions will not revert to the default limits and scale. If the new overlay or map data exceeds the current limits and scale, you are asked if you want to adjust the limits and scale. When you overlay or update maps, Surfer 7 and Surfer 8 wi ...
- How can I overlay a 3D surface map with another map, and see only the colors of the other map but with the shading of the surface map?

- How do I make contours smoother?
To smooth contours, select the Contours layer in the Object Manager. In the Property Manager, on the General tab, set the Smoothing value to something other than None. You can try Medium or High smoothing. In some cases smoothing contours via the contour properties can cause some contours to tou ...
- What's the difference between a fault and a breakline?
Breaklines occur when there are changes in slope on either side of the line. This might be at the top of a ridge or at the bottom of a river bed. Breaklines have X, Y, and Z values in the BLN file. This is the only time when Z information will be used in a BLN file. When gridding, Surfer can ...
- I export to a KML/KMZ file, but my file ends up in Africa instead of where it should be
The reason the KML or KMZ file ends up in Africa if it is not supposed to is because it was exported in page units (inches) and not map units (lat/long or other map units). This could happen if there are multiple maps in your SRF file, or if there is one map with drawn objects (points, polygo ...

- How do I grid directional data, such as wind speed and direction?
To grid directional data, follow these steps: Calculate the X and Y components of the speed/direction data in the Surfer worksheet. See below for equations. Go to Grid | Data and grid these components separately (so you have two grid files, one for speed and another for direction). Go to Map | ...
- How do I create a vector map with magnitude and direction arrows at the data points?
You can create a map showing vectors either by: 1. Creating a post map with a vector at each particular XY location using magnitude and direction data. The process will depend on if you already have the magnitude and direction data for the data points. a. You can have Surfer calc ...
- How do I make the blanked edge of a contour or image map smooth?
The jagged appearance is caused by the resolution of the grid file. When the blanking line goes through a grid cell, the entire cell is blanked. The larger the grid cells, the more jagged it will look. The smaller the grid cells, the more smooth it will look. To reduce the jagged appearance of ...
- How can I grid only the area inside my data limits?
