Constructor.
Takes a reference to a constant mesh object. To set the properties, we input a bitwise OR of the GnuPlotIO::PlottingProperties enumerations, e.g. GnuPlotIO::GRID_ON | GnuPlotIO::PNG_OUTPUT

Return/set the precision to use when writing ASCII files.
By default we use numeric_limits<Real>::max_digits10, which should be enough to write out to ASCII and get the exact same Real back when reading in.

This method may be overridden by "parallel" output formats for writing nodal data.
Instead of getting a localized copy of the nodal solution vector, it is passed a NumericVector of type=PARALLEL which is in node-major order i.e. (u0,v0,w0, u1,v1,w1, u2,v2,w2, u3,v3,w3, ...) and contains n_nodes*n_vars total entries. Then, it is up to the individual I/O class to extract the required solution values from this vector and write them in parallel.
If not implemented, localizes the parallel vector into a std::vector and calls the other version of this function.

This method should be overridden by "parallel" output formats for writing nodal data.
Instead of getting a localized copy of the nodal solution vector, it directly uses EquationSystems current_local_solution vectors to look up nodal values.
If not implemented, reorders the solutions into a nodal-only NumericVector and calls the above version of this function.

std::string libMesh::GnuPlotIO::axes_limits |
GNUplot automatically adjusts the x and y-axes of 2D plots to "zoom in" on the data.
You can set this string to force GNUplot to maintain a fixed set of axes. Example: axes_limits = "[0:1] [0:1]" would force x and y to be plotted on the range 0<=x<=1 and 0<=y<=1 regardless of where the data lie.
