Someone in the field is key as I think this is a phase diagram or similar (e.g.https://en.wikipedia.org/wiki/Phase_diagram - I can't see it well enough to be sure!) in which there are regions which can be defined in a 'big picture' which would work as a tactile
diagram, perhaps with a very limited amount of the detail added. This would give important context and for some activities could be enough but there may well be tasks in which specific curves need to be followed or values need to be read off?

<br>
Kind regards,<br>

<div>I agree with Gaeir that the most important thing is to find out from someone in that field, such as a TA or the prof, what the intended use of the diagrams is. Will the student need to pull off specific values, or just understand the general trends and
what makes one graph different from the other? If the former, you need a serious solution such as a table of values, a searchable excel file, or maybe a tactile, but if the latter, an expertly-written long description may be adequate.</div>

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">With graphs like these, it is important to understand what information is really important. In other words, is it possible to simplify the information shown? My guess is that these graphics lend themselves to
multiple sheets for a single graphic. One tactile would be the “overview,” providing the overall shape of the curves without a lot of the detail of the measurements. If the specific measurements are needed, then other graphics in sections would be useful.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">It’s good to realize that, many times, a lot of information is included in visual graphics simply because it can be. Often much of it can be simplified. You may need to speak with a content-area expert to understand
exactly what the graphic is attempting to convey. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Also remember that sometimes, for a student who is not that comfortable with tactile graphics, a simplified graphic with sighted support to describe the detail may be a good option.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">And, as John said, you can always make the graphic itself talk, which may be the best of both worlds.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
