Extending the Thermodynamic Functions To Their Full Range: Functions vs. Pressure
While finishing up the process of generating the plots of the thermodynamic functions vs. pressure I found an issue with how plots are drawn on the x-axis when the x-axis has a logarithmic scale. I calculated numeric values for every … Continue reading
Extending the Thermodynamic Functions To Their Full Range
Today I extended all 24 functions to their full range, 0-705.44 °F and 0.08866-3203.6 psi. I’ve shown the functions vs. temperature; the functions vs. pressure are generally derived from the same lines in the steam tables so the only difference … Continue reading
Testing the Thermodynamic Functions for Saturated Water As A Function of Pressure
I was getting ready to do new curve fits on all the segments of the thermodynamic functions that seemed to require it. However, I realized that I hadn’t yet plotted them all out as a function of pressure since I … Continue reading
Adding to the Graphing Capabilities
As you saw yesterday in the figure below, I’ve added the ability to plot individual points on the graph rather than a continuous function. The x- and y- locations are determined independently by transforming a value to a pixel location … Continue reading
Steam Table Functions, Curve Fitting, and Yes, the Graph Project
I’m finally detouring back to fixing the handful of errant segments in the steam table functions I created for my simulation work in the early 90s. This graph, originally posted on March 16th, shows a hiccup in the segment from … Continue reading

Graph Project: Updated To Do List
At this point I need to change direction and get back to addressing the issues which led me to create the JavaScript graph object in the first place. I’ve got enough solid functionality in place to proceed, and I’ll add … Continue reading
Graph Project: Show or Hide Graph and Axis Labels
The figures below show that the graph and axis labels can be hidden or shown independently.
Graph Project: Auto-Sizing Works — The Hard Part, Part Two
Today’s work involved getting the plot area to size itself properly when the last major tick on an axis does not fall right at the end of the axis. It turned out to be just a bit complex and it … Continue reading
Graph Project: Auto-Sizing Works — The Hard Part, Part One
Today’s updates involve ensuring that any number of axes can be properly placed on any side of the plotting area. Moreover, they will include space for tick marks that extend beyond the location of the axis itself. I also corrected … Continue reading
Graph Project: Auto-Sizing Works — The Easy Part
Today I got the main parts of the auto-sizing going again, though you can see it’s for the simple case when there is never more than one axis on a side (the support is there, I just haven’t finished the … Continue reading
