<p>Solves the differential equations with the optimised and fixed parameters

<h2>Arguments</h2>
<dl class="dl-horizontal">
<dt>x</dt>
<dd>
Alias for fit introduced for compatibility with the generic S3 method.
</dd>
<dt>fit</dt>
<dd>
An object of class <code>mkinfit</code>.
</dd>
<dt>obs_vars</dt>
<dd>
A character vector of names of the observed variables for which the
data and the model should be plotted. Defauls to all observed variables
in the model.
</dd>
<dt>xlab</dt>
<dd>
Label for the x axis.
</dd>
<dt>ylab</dt>
<dd>
Label for the y axis.
</dd>
<dt>xlim</dt>
<dd>
Plot range in x direction.
</dd>
<dt>ylim</dt>
<dd>
Plot range in y direction.
</dd>
<dt>col_obs</dt>
<dd>
Colors used for plotting the observed data and the corresponding model prediction lines.
</dd>
<dt>pch_obs</dt>
<dd>
Symbols to be used for plotting the data.
</dd>
<dt>lty_obs</dt>
<dd>
Line types to be used for the model predictions.
</dd>
<dt>add</dt>
<dd>
Should the plot be added to an existing plot?
</dd>
<dt>legend</dt>
<dd>
Should a legend be added to the plot?
</dd>
<dt>show_residuals</dt>
<dd>
Should residuals be shown? If only one plot of the fits is shown, the
residual plot is in the lower third of the plot? Otherwise, i.e. if
"sep_obs" is given, the residual plots will be located to the right of
the plots of the fitted curves.
</dd>
<dt>maxabs</dt>
<dd>
Maximum absolute value of the residuals. This is used for the scaling of
the y axis and defaults to "auto".
</dd>
<dt>sep_obs</dt>
<dd>
Should the observed variables be shown in separate subplots? If yes, residual plots
requested by "show_residuals" will be shown next to, not below the plot of the fits.
</dd>
<dt>rel.height.middle</dt>
<dd>
The relative height of the middle plot, if more than two rows of plots are shown.
</dd>
<dt>lpos</dt>
<dd>
Position(s) of the legend(s). Passed to <code>legend</code> as the first argument.
If not length one, this should be of the same length as the obs_var argument.
</dd>
<dt>inset</dt>
<dd>
Passed to <code>legend</code> if applicable.
</dd>
<dt>show_errmin</dt>
<dd>
Should the FOCUS chi2 error value be shown in the upper margin of the plot?
</dd>
<dt>errmin_digits</dt>
<dd>
The number of significant digits for rounding the FOCUS chi2 error percentage.
</dd>
<dt>&#8230;</dt>
<dd>
Further arguments passed to <code>plot</code>.
</dd>
