+#### Non interactive screen grab of the tool output
+![Plotly tabular non-interactive screengrab](pbsample.png)
+
+Specialised version of the generalised ![plotly_tabular_tool](https://github.com/fubar2/plotly_tabular_tool), but designed
+for 25 column Galaxy blastn search outputs.
+
+It uses the same code, but adds a default header and auto-transformation of the evalue column -log10(x) to make them more like the bitscore
+
+Plotly.express makes a lot of clever design decisions.
+Unfortunately, it gets totally confused with very small floats in scientific notation. Treats columns with 5.00e-204 as strings or something, so
+strange and probably uninformative axes and plots will probably result if you try a blast evalue column without transformation.
+Note that all columns used for colour (legend) and the x/y axis tickmarks are truncated because they can squish up the plot.
+*..* is appended at the truncation.
+
+## Tool made with the Galaxy ToolFactory: https://github.com/fubar2/galaxy_tf_overlay
+The current release includes this and a generic tabular version, plus a java .jar wrapper, in an "advanced example" history 
+where they can be rerun and changed. They are also generated by an "advanced expample workflow"
+where they can be regenerated if the input data sets are available.
